Monarch Gold or Leupold VX3

I am new to the forum so please forgive me if my question covers old ground. I am looking for opinions on the Nikon Monarch Gold 2.5x10 50MM (30MM tube) and the Leupold VX3 4.5x14 50MM (also 30MM tube). I have several scopes in both of these brands and am very pleased with them.
I just don't have any experience with these new offerings and wanted some opinions from those that do.
Low light performance and adequate eye relief are important to me. It's going on a special rifle I have waited along time for.
